-$PECIFIGATION forming part of Letters Patent No. 536,371, dated March 26, 1895. Application filed July 6, 1894- Serial No. 516,693. (No model.)

1'0 all whom it may concern.-

Be it known that I, ARTHUR B. CoWLEs, of Rochester, in the county of Monroe, in the State of New York, have invented new and usefullmprovements in Paper-Box Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in IO machines, particularly applicable for gluing or pasting and folding the blanks from which paper or card-board boxes are manufactured, and has for its object a particularly simple, practical, and highly effective device for the 15. desired use; and to this end it consists in the general construction and arrangement of its component parts, all as hereinafter more particularly described and pointed out in the claims. I

In describing this invention, reference is had to the accompanying drawings, forming a part of this specification,in which like letters indicate correspondingparts in all the Views. Figures 1 and 2 are, respectively, top plan and side elevation of my improved machine, the frame carrying the upper feed for the article to be folded being illustrated by dotted lines as swung upwardly out of-operative position. Fig. 3 is a longitudinal vertical sec- 0 tional view, taken on line 3-3, Fig. 1. Fig. 4 is a horizontal sectional view, taken on line 4-4, Fig. 3. Fig. 5 is an end elevation of my improved machine. Fig. 6 is a transverse vertical sectional View, taken on line 6-G, Fig. 2. Fig. 7 is a transverse vertical detail sectional view, taken on line 7-7, Fig. 1. Fig. 8 is a vertical sectional view, partly in elevation, taken on line 8-8, Fig. 7. Fig. 9 is a horizontal detail sectional view, taken on line 0 9-9, Fig.8. Figs. 10 and 11 are transverse Vertical sectional views, taken respectively on lines 10-10 and 1ll1, Fig. 4. Fig. 12 is a longitudinal detail sectional view of a modified form of glue or paste feed. Fig. 13 is an 5 isometric perspective of the detached folder of my improved machine. Fig. 14 is a top plan view of the blank from which the boxes are folded. Fig. 15 is an isometric perspec tive of the folded blank; and Fig. 16 is an isometric perspective of the folded box.

The frame A is of anydesirable' form, size,

and construction, and is provided at one end with cutting and scoring rollers B O, and a spindle D for supporting a roll E of paper or card board from which the box blank e, or the article to be folded, is cut.

The box blank 6 is formed with right angularly arranged side and front and rear edges e a e 6 and with a lip e projecting from the edge 6 The blank 6 is provided with cuts or slits e extending inwardly from its front and rear edges 6 e and arranged substantially parallel with its side edges 6' e and with right angularly arranged scores e a con necting opposite cuts or slits e and extending from the front and rear edges of the lip e in planes substantially parallel with the front and rear edges 6 e The roll 13 is provided with annular an radial knives b b suitably arranged to cut the blank (2 from the feeding end of the roll E, and to form the cuts or slits e and the scores e7 e The roll 0 is provided with a series of annular and radial grooves c 0 arranged to register with-the knives b b as the blank 6 is formed. I The roller B is driven by a chain F passing over chain Wheels f b provided, respectively, upon a shaftf' and the shaft b of the roller B, and suitable gears B 0' connect the rollers B O for driving both at uniform speed. Adjusters F of any desirable construction, here illustrated as headed screws, are utilized to vary the amount of separation of the rollers B O.

The frame A is provided with a support or cross bar A for the feeding end of the roll E arranged between the rollers B C and the spindle D in a plane above the spindle D and substantially coincident with the contiguous portions of the peripheries of the rollers B 0. Suitable shoulders A are mounted upon the supporting cross bar A, and are adjustable toward and away from each other for properly aligning the feeding end of the roll-E with the knives of the cutting and scoring rollers. These shoulders A may be held in their adjusted positionby any suitable form of clamping means, as headed screws A The spindle D is removably mounted in open slots in the ends of separated arms A A sa a arranged beneath the plane of the support or cross bar A, and, as clearly seen at Figs. 1, 4:, and 11, is provided with annular shoulders 61 (I, one of which is adjustably held in position by a clamp or screw cl. The front end of the spindle D is screw threaded, and is provided with a stationary adjusting nut D supported in the slotted end of the adjacent arm A and a stop nut D It is thus evident that the spindle D may be adjusted lengthwise for aligning the roll E with the guide shoulders A A and the cutting and scoring rollers B C, and that said spindle may be readily removed or placed in operative position.

The blanks 6 cut from the feeding end of the roll E by the rollers B C are engaged by upper and lower feeds for conveying the same to the gluing or pasting and folding mechanisms of tny improved machine. The lower feed preferably consists of a pairof separated belts G G arranged in proximity to the rollers B C and asecond belt G extending beyond the belts G G and having one extremity interposed between the adjacent ends of the belts G G. The uppermost portions of the belts G G G extend in planes substantially coincident with the support or cross bar A, previously described, and said belts move slightly faster than the contiguous portions of the rollers B C for separating the adjacent edge of the last severed blank 6 from the next adjacent blank when engaged by the rollers B (3 during its formation, as clearly seen at Figs. 1, 2, and 3.

The ends of the belts G G adjacent to the rollers 13 C are passed over pulleys g g upon a shaft journaled in the frame A, and the opposite ends of said belts are passed over a pulley 9 formed of less diameter than the rollers B C and mounted on the shaftf, previously described. The diameter of the pulley g is considerably greater than that of the pulleys g g, and the pulleys g g are arranged in close proximity to the cutting and scoring rollers B C. The end of the belt G interposed between the adjacent ends of the belts G G is also passed over the pulley g and its opposite end is passed around a drum 9 of considerable size mounted on a shaft g journaled in the corresponding end of the frame A. The part of the uppermost portion of the belt G interposed between the pulleys g and the drum g is supported by suitable driving pulleys and idlers 9 9 journaled in the frame A,and the opposite portion of the belt G is supported by a frictionaliy driven pulley g and the lower face of adriving pulley g, which is formed of greater diameter than the idlers The shaft is provided with a pulley g to which power is communicated by any suitable means as a belt g and the belt G oommunicates motion to the pulley g and operates the belts G G, and also rotates the.

cutting and scoring rollers B 0 through the medium of the shaft f and the power transmitting mechanism, previously described, in-

terposed between the shaft f and the roll ers B O.

The upper feed for the blanks e or the articles to be folded consists of separated belts H H supported directly above the belts G G, previously described, and a belt I-I above the end of the belt G adjacent to the belts G G. The belts H H are passed over pulleys h h 7L3 arranged above the pulleys g gg previously described, and mounted. respectively, upon shafts b h. The belt h is passed over pulleys 71. 71 upon shafts it it journaled ina frame I.

The shaft 7:. is journaletl in the frame I and the shaft 7L is journaled in the free ends of arms 1; having their rear ends pivoted at t" to the frame I and their intermediate portions secured in operative position by suitable clamps i The opposite end of the frame I is hinged at i to the frame A, and said frame is free to be moved or swung upwardly into its position indicated by dotted lines at Fig. 2 for permitting access to the underlying parts. The bearings for the shafts 7t 7L7 and h are all preferably adjusted vertically by suitable adjusters as headed screws h and the shaft h is adjusted toward and away from the underlying shaft for varying the frictional power of the belts H II, by loosening the clamps 2' swinging on the pivots i the arms carrying said shaft, and then forc ing the clamps 11 to operative position.

The belts H H H are driven by suitable gears 71. h h h connecting the shafts h h" and the underlying shafts f and 9 provided respectively with the pulleys g Q12. The shafts f g are connected by gears h It h for driving both simultaneously.

The blanks, when engaged by the-upper and lower feeds of my invention are passed beneath a suitable folder Jsecured to the frame I and consisting of opposite longitudinal sections j j adjustably secured together by clampsj The folder J is formed with separated longitudinal bars having their opposite ends provided with laterally extending arms detachably secured together and forming front and rear cross bars j j and is provided with asupporting cross barj having upturned slotted endsj adj nstably secured by suitable clampsj to the frame I. The folderJ is thus adjustable in width and is also adjustable vertically. Feeding of the blanks e, or the articles to be folded, beneath the folder J is facilitated by passing the lowermost portion of the belt H beneath the front cross barj of the folder and upwardly through a central aperturej in the folder.

Arranged at opposite sides of the folder J are twisted belts K K passing over vertically moving pulleys it is mounted on a shaft 7c provided with the smaller driving pulley g, and vertically moving pulleys k 70 mounted on a shaft 71: journaled ,in the frame A. The adjacent sides of the pulleys k 70 are arranged directly beneath the corresponding end of the folder J and the top face of the feeding belt are separated a greater distance than the width of the belt G and are disposed in proximity to the adjacent portions of the longitudinal edges of the feeding belt G as clearly seen at Figs. 1 and 7.

The central portions of the blanks e are firmly engaged by suitable pressure rollers Z Zmounted in a movable frame L supported by the frame I and forced into operative position by a spring Z.

M M are revolving disks, Figs. 1, 2, 7, and

8 arranged on opposite sides of the folder and the feeding belt G at an angle with thelength- Wise plane of the folder and having their ad-1 jacent edges slightly elevated above thetop. faces of the outer edges of the folder, as best seen at Fig. 7. The lower or engaging faces of the disks M as also seen at Fig. 7 are arranged at dissimilar angles with the engaging faces of the folder and the feeding belt G for insuring the desired lapping upon each other of the projecting edges of the feedingblanks,

and said disks are mounted on spindles m m journaled in bearings m movable lengthwise of a cross bar A of the frame A. Suitable clamps M hold the bearings m in their adjusted position. The beltsK Kare passed beneath the disks M after the edges 6' e of the feeding blanks are elevated,and said belts held in operative position by said disks for turning the edges 8' e inwardly over the interposed portion of the folder J and lapping said edges upon each other and the adjacent portions of the blanks.

As previously stated, the edges 6 e of the feeding blanks e are first elevated by the belts K K, and are then lapped upon the folder J by said belts. It is extremely desirable to fasten the edges e 6 together, and consequently the lip e is provided with paste or glue, which is applied by a suitable feed before the blank eis engaged by the belts K The preferable form of feed consists of a retary disk N arranged at one side of the advanced end of the belt (1 and movable in a reservoir n for containing glue or paste. The level of the glue or paste may be adjusted by aspiral spring or folding plate n, and the adjusting screw 12 for withdrawing said spring or plate from the reservoir 71. and forcing the 'same thereinto, as shown in the modified form of glue or paste feed illustrated at Fig. 12. A suitable heater N mounted on an adjustable support N may serve to constantly heat the reservoir 12.. After passing beyond the disks- M M the partially folded blanks pass beneath the rollers 16 10 which firmly press or fold their longitudinal edges, which are then'substantially coincident with the outermost scores 6 e A suitable yielding pressure plate 0 then firmly presses the central portion of the folded blanks, and forces the glued or pasted lip e firmly against the underlying portion of the edge e. The plate 0 is mounted on a plunger 0 reciprocally movable in a hinged cross bar A and provided with a spring 0 for forcing the plate 0 toward the underlying portion of the belt G I preferably use an auxiliaryfeeding belt P for squeezing the folded blanks and aiding the belt G to feed the folded blanks beneath the drum g to a second auxiliary feed consisting of a downwardly inclining belt R arranged beneath the folder and the belt G at one side of the drum and extending transversely across the frame A at substantially right angles with the belt G The central portion of the belt Pis passed around pressure pulleys 19 arranged concentric with the adj acent portion of the drum 9 and provided with suitable adj usters p of any'desirable form, size, and construction for forcing the pulleys 19 toward and away from the belt G The inner face of the belt P is thus arranged concentric with the drum 9", and the'opposite ends of said belt are passed aroundthe pulley g and the pressure pulley 19 which is arranged above the pulley g and the drum 9, and is also provided with a stationary adjuster 19 The second auxiliary feeding belt R is movable over pulleys r 'r, and the shaft for the roller r is connected by miter gears r to the shaft of the drum g which is frictionally driven by the under portion of the belt G The blanks, folded as illustrated at Fig. 15,

and having their lips e gluedor'pasted to their edges 6', are fed from this second auxiliary feed, and may then be folded by hand or otherwise to form the complete box, as shown at Fig. 16.

The operation of my invention will bereadily perceived upon reference to the foregoing description and the accompanying drawings,

and it will be particularly noted that a con-' tinuous roll'of paper or card-board is cut into a series of blanks, that these blanks. are slightly separated from each other and are suitably cut and scored to form paper or cardboard boxes; that in their progress through the machine one of the edges of the blanks is provided with glue or paste, and this edge and the opposite edge are folded upon the'inclosed portion of the blank, and are firmly secured together. 7

The construction of the machine is such that itoperates automatically and with great rapidity, is highly durable and eiiicient, and permits ready access to the parts and adjustment of the feeding devices. It is evident, however, that the detail construction and arrangement of my improved machine may be considerably varied without departing from the spirit thereof, and consequently I donot IIO herein specifically limit myself to such exact detail construction and arrangement.
